Start when the kids are young, show them how great nature can be so they SEE it for themselves. As they grow older, slowly include them in more and more of the planning so they are busy DOING the adventure planning. Eventually, have them actuall DO the planning. This was a trip planned entirely by my now-adult son. This was my Father’s Day, after summiting Snowslide Pass/Peak and “skiing” down to the lake. The weather was nice, but ice was still floating, and the lake froze again that night. He’s mostly off on his own now, but he still takes the time to pull his dad into the mountains.
